Description

  The present invention relates to a driving evaluation device, a driving evaluation system, and a driving evaluation method for evaluating driving from the viewpoint of suppressing unnecessary fuel consumption.

  Conventionally, the fuel consumption when driving that deteriorates fuel consumption such as excessive acceleration is compared with the fuel consumption when driving that deteriorates fuel consumption such as excessive acceleration is not performed. A technique for evaluating the operation based on the fuel consumption excessively consumed by the worsening operation is known (see Patent Document 1).

JP 2002-362185 A

  However, the conventional technique has a problem that the operation at the time of deceleration cannot be evaluated because the operation is evaluated based on the fuel consumption excessively consumed due to excessive acceleration or the like.

The present invention sets a predetermined evaluation section at the time of deceleration based on a change with time of the vehicle speed of the vehicle, and according to the evaluation fuel consumption consumed in the evaluation section calculated based on the fuel consumption over time. The above problem is solved by evaluating driving.

According to the present invention, since unnecessary fuel consumption can be obtained in an evaluation section set based on a change in vehicle speed, driving during deceleration can be evaluated.

The driving evaluation information providing apparatus 100 according to the first embodiment evaluates a driver's driving from the amount of fuel consumed during deceleration, and provides the driver with information useful for improving driving technology from the viewpoint of environmental protection. It is.

  FIG. 1 is a block configuration diagram of an in-vehicle device 1000 including a driving evaluation information providing device 100 according to the present embodiment. As shown in FIG. 1, the in-vehicle device 1000 of this embodiment includes a driving evaluation information providing device 100, a navigation device 200, a vehicle controller 300, a fuel injection sensor 400, and an in-vehicle sensor 500. As shown in the figure, a driving evaluation information providing device 100 mounted on a vehicle, a navigation device 200, a vehicle controller 300, a fuel injection sensor 400, and an in-vehicle sensor 500 are a CAN (Controller Area Network) 600 and other in-vehicle devices. They are connected by LAN and exchange information with each other.

  As shown in FIG. 1, the driving evaluation information providing apparatus 100 according to the present embodiment includes a control device 10, a display 20, and a database 30 in which information necessary for driving evaluation is accumulated.

  The control device 10 of the present embodiment evaluates driving, and a ROM (Read Only Memory) 12 in which a program for executing a process of providing information related to the evaluation result to the driver is stored. By executing the stored program, a CPU (Central Processing Unit) 11 as an operation circuit functioning as the driving evaluation information providing device 100 and a RAM (Random Access Memory) 13 functioning as an accessible storage device are provided. Prepare. As an operation circuit, instead of or in addition to the CPU (Central Processing Unit) 11, an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array). Etc. can be used.

  The control device 10 includes a vehicle speed acquisition function that acquires the vehicle speed of the vehicle being driven over time, a fuel consumption acquisition function that acquires the fuel consumption of the vehicle over time, and changes in the acquired vehicle speed over time. On the basis of the first time when the vehicle starts to decelerate and becomes less than the first predetermined speed, and after the first time, the second predetermined speed is less than the second predetermined speed. Based on the evaluation interval setting function for setting the evaluation interval based on the second time when the vehicle starts to decelerate again, and the evaluation fuel consumption of the vehicle in the set evaluation interval based on the acquired fuel consumption over time An evaluation fuel consumption calculation function for calculating the vehicle, an evaluation function for evaluating the operation based on the calculated evaluation fuel consumption in the evaluation section, and an output control function for outputting the evaluation result of the operation. Moreover, the control apparatus 10 is provided with the positional information acquisition function which acquires the driving | running | working position of a vehicle with time as needed. The control device 10 executes each function by cooperation of software for realizing the function and the hardware described above.

  Hereinafter, functions realized by the control device 10 of the driving evaluation information providing device 100 will be described.

  First, the vehicle speed acquisition function of the driving evaluation information providing apparatus 100 will be described.

  The control device 10 acquires the vehicle speed of the vehicle being driven over time. A vehicle speed sensor 501 detects the vehicle speed of the traveling vehicle. The vehicle speed sensor 501 associates the detected vehicle speed with the detection timing and outputs the vehicle speed via the CAN 600 at a predetermined cycle (N milliseconds). The control device 10 acquires the vehicle speed and detection time sent from the vehicle speed sensor 501 via the CAN 600 and stores them in the RAM 13 or the database 30 of the control device 10. Since the vehicle speed detected every moment can be associated with the time detected by the timer 505, the control device 10 can observe a change in the vehicle speed over time. Note that the detected vehicle speed and the detection timing may be temporarily stored in the memory 302 of the vehicle controller 300. In this case, the control device 10 accesses the memory 302 and acquires the detected vehicle speed and detection time.

  Next, the fuel consumption acquisition function of the driving evaluation information providing apparatus 100 will be described. The control device 10 acquires the fuel consumption amount of the running vehicle over time. The fuel consumption of the traveling vehicle is detected by the fuel injection sensor 400. The fuel injection sensor 400 associates the detected fuel injection amount with its detection timing and outputs the fuel injection sensor 400 through the CAN 600 at a predetermined cycle (N milliseconds). The control device 10 acquires the fuel injection amount sent from the fuel injection sensor 400 via the CAN 600 and the detection timing thereof, and stores them in the RAM 13 or the database 30 of the control device 10.

  In addition, the control device 10 acquires the fuel consumption amount of the traveling vehicle from the vehicle controller 300. The vehicle controller 300 according to the present embodiment processes an electrical signal corresponding to a physical quantity detected by the in-vehicle sensor 500 according to a preset program, and outputs the resulting electrical signal to an actuator system. unit). The vehicle controller 300 calculates the amount of fuel (gasoline) required to reach a predetermined air-fuel ratio using the detected amount of air taken in by the engine, opens the injection valve, and transfers the fuel (gasoline) into the intake pipe. Alternatively, electronic fuel injection (EFI) to be supplied to the combustion chamber is executed. If the air-fuel ratio is constant, [air-fuel ratio = air mass / fuel mass], so the vehicle controller 300 can determine the required fuel injection amount if the intake air mass can be measured. Further, the vehicle controller 300 controls the fuel injection amount of the injector that controls the fuel supply amount by the energization time of the electromagnetic coil of the injector. For this reason, the amount of fuel consumed during travel is determined based on the fuel injection time (the length of on-time time of PWM (Pulse Width Modulation) control) included in the command value issued by the vehicle controller 300. it can. When the vehicle controller 300 performs electronic fuel injection (EFI), the state of the engine (such as when the engine starts), the detected value of the accelerator opening sensor 502, the detected value of the shift sensor 503, Although the fuel injection amount is controlled while performing appropriate correction according to the detection value of the brake sensor 504, the specific control method of the fuel injection amount is not particularly limited, and the method used at the time of filing can be used.

  When the vehicle controller 300 executes electronic fuel injection (EFI), the vehicle controller 300 stores the command value related to the control of fuel injection and the execution timing of the command in the memory 302 in association with each other. That is, the memory 302 stores the command value for specifying the fuel injection amount emitted by the vehicle controller 300 over time. This command value may be an on-time period of a pulse command value of PWM (Pulse Width Modulation) control corresponding to the fuel injection amount or the fuel injection amount.

  The control device 10 acquires the history of the fuel injection amount of the command value stored in the memory 302 of the vehicle controller 300 over time as the history of fuel consumption. When the command value is the on-time time of the pulse command value, the control device 10 determines the injection amount stored in the memory 302 and the pulse width of the command value (on-time time) based on the pulse width (on-time time) of the command value. The fuel injection amount (that is, the fuel consumption amount) is calculated with reference to the injection amount map 31 which is a conversion table in which the (on-time time) is previously associated.

  In addition, the position information acquisition function of the driving evaluation information providing apparatus 100 will be described. The control device 10 acquires the traveling position of the vehicle over time as necessary. This positional information is for specifying and indicating the place where the driving evaluation is performed when the driving evaluation result is provided later to the driver. By identifying the specific location and presenting the evaluation result, the driver can examine the evaluation result in correspondence with his / her driving situation, so use the evaluation result as data for improving driving. be able to.

  The control device 10 acquires the travel position of the vehicle over time from the navigation device 200 over time.

  The navigation device 200 includes a GPS (Global Positioning System), and detects a traveling position (latitude / longitude) of a traveling vehicle. In addition, the navigation device 200 includes coordinates of latitude and longitude such as attributes of travel positions (including POI: Point Of Interest such as address or intersection name, facility name, and so on). With reference to the electronic map data 201 defined by the value, the traveling position of the vehicle and / or the attribute of the traveling position is determined. And the navigation apparatus 200 matches the detected driving | running | working position of a vehicle and / or the attribute of a driving | running | working position, and detection time, and memorize | stores it in the memory 202 of the navigation apparatus 201. FIG. The control device 10 acquires the travel position and the timing at which the travel position is detected from the navigation device 200 via the CAN 600 over time.

  Next, the evaluation section setting function of the driving evaluation information providing apparatus 100 will be described. Based on the change over time of the acquired vehicle speed, the control device 10 detects the first time when the vehicle starts to decelerate and falls into the acceleration state until the vehicle becomes less than the first predetermined speed. After the first time, the evaluation section is set at a second time when the vehicle starts to decelerate again at a speed less than the second predetermined speed.

  Based on FIG. 2, an example of an evaluation section setting method set by the control device 10 will be described. FIG. 2 shows changes in the vehicle speed over time, showing the acquired vehicle speed and the time at which the speed was detected in association with each other. An example of the change in the vehicle speed shown in FIG. 2 will be described. At the beginning of observation, the vehicle speed of the vehicle exceeds 40 km / h. That is, the vehicle speed of the vehicle is a preset speed threshold value of 20 km / h or more. Thereafter, the vehicle starts to decelerate. The vehicle speed of the vehicle decreases with the passage of time, and the speed of the vehicle becomes less than a preset speed threshold of 20 km / h at timing P1. The vehicle further decelerates, but at a first time T1 before the vehicle falls below a first predetermined speed (for example, 5 km / h), the vehicle speed changes from the deceleration state to the acceleration state. In addition, after the first time (T1), the vehicle starts to decelerate again at a second time (T2) in a state of less than a second predetermined speed (for example, 20 km / h). Thereafter, the vehicle decelerates and enters a stopped state (vehicle speed = 0 km / h).

  The control device 10 of the present embodiment sets the evaluation interval between the first time (T1) and the second time (T2) (the interval indicated by the arrow in FIG. 2), and evaluates the operation in this evaluation interval. Do.

  When observing the change in the vehicle speed over time shown in FIG. 2, the vehicle depresses the accelerator between the first predetermined speed and the second predetermined speed, after decelerating, such as depressing the brake or releasing the accelerator, and again before stopping. It can be inferred that there was an acceleration operation such as stepping on. When the automobile decelerates, acceleration during deceleration in the low speed zone is unnecessary, and the fuel required for acceleration in the deceleration process in the low speed zone is unnecessary. For this reason, in this embodiment, the fuel consumption amount in the deceleration process in the low speed zone shown in FIG. 2 is determined as unnecessary fuel consumption.

  Such a driving situation occurs when the distance between the preceding vehicle and the preceding vehicle is short. In the present embodiment, unnecessary fuel consumption due to reacceleration during deceleration is detected by appropriately setting the evaluation section. For this reason, in the present embodiment, the evaluation section is set only when the vehicle is in a low speed range from the first predetermined speed to less than the second predetermined speed. That is, it occurs in acceleration that occurs during deceleration that is less than the first predetermined speed or does not lead to a stop state (acceleration that is repeated with deceleration under traffic congestion), or deceleration that occurs in a high vehicle speed zone that is higher than the second predetermined speed. Acceleration (for example, an acceleration in which the signal changes from red to blue while decelerating and increases the speed) is regarded as an acceleration necessary for traveling and is not an object of the driving evaluation of this embodiment. Note that the first predetermined speed and the second predetermined speed can be arbitrarily set. For example, the first predetermined speed is set to a value of 1 km / s to 5 km / s, and the second predetermined speed is set to a value of 10 km / s to 30 km / s.

  Furthermore, the control device 10 of the present embodiment provides a speed threshold when setting the evaluation section, and sets the evaluation section when the speed of the vehicle becomes less than the speed threshold from a speed equal to or higher than a preset speed threshold. . The speed threshold is set when setting the evaluation section in this way, because acceleration and deceleration frequently occur in traffic jams, so it is difficult to evaluate unnecessary fuel consumption. From the above, only when the speed is less than the predetermined speed threshold, the evaluation section is set and the driving is evaluated. That is, when a vehicle traveling on a congested road accelerates during deceleration, it is excluded from the target of driving evaluation according to the present embodiment. Accordingly, acceleration during deceleration can be evaluated as unnecessary fuel consumption only in a situation where fuel is wasted, not in an unavoidable situation such as traffic congestion. The predetermined speed threshold can be set arbitrarily. For example, the predetermined speed threshold is set to a value of 10 km / s to 40 km / s. This speed threshold value may be the same value as the second predetermined speed, or may be a value equal to or higher than the second predetermined speed.

  Furthermore, the control device 10 of the present embodiment sets the second time when the speed increases by a predetermined value or more after the first time. As shown in FIG. 2, the control device 10 sets the timing at which the speed increases by a predetermined value R or more from the vehicle speed at the first time (T1) as the second time (T2), and sets the first time ( The period from T1) to the second time (T2) is set as the evaluation interval. That is, the control device 10 according to the present embodiment does not evaluate the driving when the speed increase amount after the deceleration starts is less than the predetermined value. Specifically, the control device 10 of the present embodiment sets a value R as a threshold value for the increase amount of the vehicle speed, and the timing when the increase amount of the vehicle speed after the first time becomes equal to or greater than the threshold value R is set as the second time. The driving is evaluated for the evaluation section in between. As a situation where a small amount of acceleration occurs after deceleration, there is a case where a speed increase occurs due to creep running after releasing the brake pedal after deceleration. In the present embodiment, since acceleration after deceleration due to creep running is excluded from the object of driving evaluation, only when there is a speed increase equal to or greater than a predetermined threshold R (speed increase amount threshold) after the first time. The second time and the evaluation section are set. The predetermined value R is not particularly limited, but is 5 km / h in the present embodiment. Since the acceleration that naturally occurs due to the creep phenomenon is about 5 km / h, if the speed increase is less than 5 km / h, it is regarded as acceleration due to the creep phenomenon, and unnecessary fuel may be consumed. Judge that it is not an evaluation section. This makes it possible to evaluate acceleration during deceleration as unnecessary fuel consumption only in a situation where fuel is wasted, not in an unavoidable situation such as creep running.

  Next, the evaluation fuel consumption calculation function of the driving evaluation information providing apparatus 100 will be described.

  The control device 10 calculates the evaluation fuel consumption amount of the vehicle in the set evaluation section based on the fuel consumption amount with time acquired by the fuel consumption amount acquisition function. That is, the fuel consumed between the first time (T1) and the second time (T2) is calculated as the evaluation fuel consumption. In FIG. 2, the sum of the fuel injection amounts (the integrated value of the fuel injection amounts from the first time (T1) to the second time (T2)) surrounded by the one-dot chain line is calculated as the evaluation fuel consumption amount.

  As described above, the control device 10 acquires the fuel injection amount and the detection timing thereof from the fuel injection sensor 400, so that the fuel injection amount at each timing is determined from the first time (T1) to the second time. Until the time (T2) is calculated, and the evaluation fuel consumption of the vehicle in the evaluation section is calculated. The same applies to the case where the control device 10 acquires the fuel injection amount and its detection timing from the vehicle controller 300. Furthermore, when the control device 10 acquires the pulse command value (control on-time time length) of fuel injection control and the execution timing of the command from the vehicle controller 300, the injection amount map 31 stored in the database 30 in advance. First, an injection amount corresponding to a pulse command value (control on-time time length) for fuel injection control is calculated. Then, the fuel injection amount corresponding to each pulse command value is integrated from the first time (T1) to the second time (T2), and the evaluation fuel consumption amount of the vehicle in the evaluation section is calculated. The injection amount map 31 includes information associating a pulse command value (control on-time time length) defined for each vehicle type with the fuel injection amount.

  The control device 10 stores the calculated evaluation fuel consumption in the RAM 13 or the memory of the database 30. Further, the control device 10 integrates the evaluation fuel consumption for each predetermined traveling unit. That is, the control device 10 may integrate the evaluation fuel consumption calculated in one run from the ignition key-on (engine start) to the ignition key-off (engine off), or one day, one week, one month, etc. The estimated fuel consumption calculated during the calendar deadline may be integrated. Further, the control device 10 sets the current position (latitude / longitude) of the host vehicle detected by the navigation device 200 by the navigation device 200 until the host vehicle reaches the destination. The estimated fuel consumption calculated until it substantially coincides with the destination (latitude / longitude) may be integrated.

  A driving tendency can be derived by integrating a plurality of evaluation fuel consumption amounts.

  Next, the evaluation function of the driving evaluation information providing apparatus 100 will be described. The control device 10 evaluates the operation based on the evaluated fuel consumption amount in the calculated evaluation section. Although the evaluation criteria can be arbitrarily defined, the control device 10 of the present embodiment is not good at driving during deceleration when the evaluation fuel consumption in the evaluation section is equal to or greater than a predetermined threshold (or a positive value). It is evaluated that necessary fuel has been consumed, and if the evaluation fuel consumption amount in the evaluation section is less than a predetermined threshold (or zero), it is evaluated that fuel unnecessary for driving during deceleration has not been consumed. The predetermined threshold can be defined in advance, and the predetermined threshold may be set for each vehicle type and each user based on the vehicle type identification information and the user identification information.

  Finally, the output control function of the driving evaluation information providing apparatus 100 will be described.

  The control device 10 outputs an operation evaluation result based on the evaluation fuel consumption amount in the calculated evaluation section via the display 20. Moreover, although not shown in figure, the control apparatus 10 outputs the driving | running evaluation result via the speaker with which the navigation apparatus 200 and the audio apparatus of a vehicle are provided.

  Further, the control device 10 may output the evaluation result only when it is evaluated that the fuel unnecessary for driving during deceleration is consumed.

  FIG. 3 is a diagram illustrating an example of a display mode of an evaluation result of driving according to the present embodiment. As shown in FIG. 3, the control device 10 according to the present embodiment outputs the evaluation result including the time when traveling in the evaluation section, the information indicating the evaluation section, and the evaluation fuel consumption in the evaluation section. The time when traveling in the evaluation section is the first time (T1), the second time (T2), or the second time (from the first time (T1) detected when setting the evaluation section ( Time until T2). In the example shown in FIG. 3, “September 20, 18:35:35” corresponds to the time when the vehicle travels through the evaluation section. Further, the information indicating the evaluation section is information for specifying a place where the host vehicle travels and the evaluation section is set. The place where the evaluation section is set is the travel position of the vehicle detected by the navigation device 200 at the first time (T1) or the second time (T2). The travel position may be expressed by latitude / longitude, but is expressed by an address or point attribute (POI information such as an intersection name or facility name) corresponding to the latitude / longitude in the electronic map data 201 of the navigation device 200. May be. In the example illustrated in FIG. 3, “near the Mita Minami intersection in Atsugi City, Kanagawa Prefecture” corresponds to information indicating the evaluation section. Moreover, as shown in FIG. 3, a map image (map information) including an evaluation section may be presented on the display 20. Furthermore, the evaluation fuel consumption amount in the evaluation section is the evaluation fuel consumption amount calculated by the evaluation fuel consumption amount calculation function. In the example shown in FIG. 3, “5 cc of fuel wasted wasted” corresponds to information indicating the evaluation fuel consumption. Furthermore, the control device 10 presents driving advice corresponding to the evaluation result. In the example shown in FIG. 3, “Let's make a smooth deceleration with a margin in the inter-vehicle distance” corresponds to the driving advice associated with the determination result that there was unnecessary fuel consumption during deceleration.

  In this way, by specifying the specific driving date and time and driving time and presenting the evaluation result, the driver can examine the evaluation result in association with his / her driving situation, so as to improve driving The evaluation results can be used as materials.

  Then, the control procedure of the driving | operation evaluation information provision apparatus 100 of this embodiment is demonstrated.

  FIG. 4 is a flowchart for explaining the entire process of presenting the evaluation results of driving in the present embodiment.

  As shown in FIG. 4, when the ignition key is turned on or a start command for this driving evaluation function is input, first, in step S <b> 01, the control device 10 acquires the vehicle speed detected by the vehicle speed sensor 501 over time. In parallel with this, in step S02, the control device 10 acquires the fuel injection amount detected by the fuel injection sensor 400 (or the vehicle controller 300) over time. Similarly, in parallel with these, in step S03, the control device 10 acquires the travel position of the vehicle detected by the navigation device 200 over time. Each of these pieces of information is stored in the RAM 13 or the memory 32 of the database 30 in association with a common time axis.

  In subsequent step S04, the control device 10 determines whether or not the vehicle speed has been reduced to less than 20 km / h from a predetermined speed threshold value of 20 km / h or higher. When the vehicle speed decelerates to less than 20 km / h from a state where the vehicle speed is 20 km / h or higher, the control device 10 proceeds to step S05 and starts the driving evaluation process.

  In step S05, the control device 10 extracts an evaluation section based on the vehicle speed with time acquired in step S01. The evaluation section includes the first time when the vehicle starts to decelerate to the acceleration state before the first predetermined speed (for example, 0 km / h to 5 km / h) and the first time. Is less than the second predetermined speed (10 km / s to 20 km / s) and is between the second time when the vehicle starts to decelerate again.

  In step S06, the control device 10 calculates the fuel consumption amount in the evaluation section. Specifically, the control device 10 evaluates the integration amount of the fuel injection executed from the first time to the second time based on the elapsed fuel injection amount acquired in step S02 in the evaluation section. Calculated as fuel consumption.

  Moreover, in step S07 parallel to this process, the control apparatus 10 specifies the positional information on an evaluation area. Specifically, the control device 10 specifies an address or intersection name, facility name, etc. that identifies a travel position that travels between the first time and the second time based on the travel position with time acquired in step S03. The POI information of is acquired.

  In the next step S08, the control device 10 evaluates the operation. Specifically, when the fuel consumption amount in the evaluation section is greater than or equal to a predetermined value, the control device 10 evaluates that the operation at the time of deceleration is not an operation that contributes to environmental protection (so-called eco-operation). On the other hand, when the fuel consumption amount in the evaluation section is less than the predetermined value, the control device 10 evaluates that the operation at the time of deceleration is an operation that contributes to environmental protection (so-called eco operation).

  Thereafter, in step S09, the control device 10 determines whether or not traveling has ended. Specifically, when acquiring the ignition key-off information, the control device 10 determines that the travel has ended, and proceeds to step S10. On the other hand, if the control device 10 does not acquire the ignition key-off information, the control device 10 determines that traveling is continuing, and returns to step S01.

  In step S10, the control device 10 presents the driving evaluation result. The evaluation results presented are both evaluations that the driving at the time of deceleration is not driving that contributes to environmental protection (so-called eco-driving) and that the driving at the time of deceleration is driving that contributes to environmental protection (so-called eco-driving). Including.

  Next, a specific method for calculating the evaluation fuel consumption will be described with reference to FIGS. 5 and 6. FIG. 5 is a flowchart for explaining the calculation processing of the fuel consumption in the evaluation section by the driving evaluation information providing apparatus 100. FIG. 6 shows the calculation processing of the fuel consumption in the evaluation section shown in FIG. It is a figure for demonstrating the timing to be called. Portions overlapping with the processing shown in FIG. 4 will be briefly described.

  As shown in FIG. 5, first, in step S101, the control device 10 starts this processing when it is determined that the vehicle speed has been reduced to less than 20 km / h from a state where the speed threshold is 20 km / h or higher.

  In step S102, the control device 10 ends the process when the vehicle speed becomes 20 km / h or more, and proceeds to step S103 when the vehicle speed is less than 20 km / h. Point A shown in FIG. 6 shows the timing when the vehicle speed is 20 km / h or higher, and point B shown in the figure shows the timing when the vehicle speed is less than 20 km / h. When these two points of information are obtained, the control device 10 determines that the vehicle has entered a deceleration state that is a target for driving evaluation.

  In step S103, the control device 10 determines whether or not the vehicle speed of the vehicle is 0 km / h. In this embodiment, the presentation timing of the driving evaluation result is set as the vehicle stop timing. For this reason, when the vehicle speed becomes 0 km / h, the process proceeds to step S107 and subsequent steps, and a process for presenting the evaluation result of driving is executed.

  In step S107, the control device 10 determines whether or not the calculated evaluation fuel consumption is a positive value. If the evaluation fuel consumption is zero, the process is terminated, and if the evaluation fuel consumption is positive, that is, if it is evaluated that unnecessary fuel is consumed during deceleration, the process proceeds to step S108.

  In step S108, the control device 10 informs the user of the position such as the evaluation fuel consumption calculated during one travel, the date and time when the vehicle traveled through the evaluation section, the address of the evaluation section, and POI information in the vicinity. The attribute is presented on the display 20 (see FIG. 3).

  On the other hand, until the vehicle speed reaches 0 km / h, the control device 10 repeats the calculation process of the evaluation fuel consumption after step S104.

  Hereinafter, the calculation process of the evaluation fuel consumption will be described.

  First, in step S104 and step S109, when the vehicle is traveling at a speed of less than 20 km / h from a speed exceeding the vehicle speed of 0 km / h, the control device 10 determines the first timing when the vehicle speed of the vehicle increases. Detect as time.

  That is, if there is an increase in vehicle speed in step S104, the process proceeds to step S109, and it is determined whether or not this increase in vehicle speed is a newly detected increase in vehicle speed. Whether or not the increase in the vehicle speed is new is determined based on the stored vehicle speed data over time. If there is a new increase in the vehicle speed, the timing is set to the first time, and the process proceeds to step S112. In the example shown in FIG. 6, a new increase in vehicle speed is observed when the vehicle speed changes from point C to point D in FIG. That is, the time at point C is the first time.

  In step S112, the control device 10 determines the first time, the vehicle speed at the first time, the initial value zero which is the maximum increase in vehicle speed at the first time, and the coordinates of the travel position at the first time. (Latitude / longitude) is stored in the RAM 13 in association with the first time. When the initial monitoring value is registered at the first time, the process returns to step S104 and the vehicle speed is observed again.

  If the vehicle speed further increases after the new vehicle speed increase, for example, at point D in FIG. 6, the control device 10 determines an increase in the vehicle speed in step S104, and determines in step S109 that it is not a new vehicle speed increase. move on.

  In step S110, the control device 10 calculates the increase amount of the current vehicle speed. The control device 10 obtains the speed difference X from the vehicle speed increase amount (difference X) "=" current vehicle speed (vehicle speed at point D) "-" vehicle speed at the first time (vehicle speed at point C) ". The fuel used for driving the vehicle that generates the difference X is the fuel consumption to be evaluated In this process, the controller 10 determines that the current vehicle speed is less than the second predetermined speed (20 km / s). If the current vehicle speed is equal to or higher than the second predetermined speed (20 km / s), the process is stopped and the process returns to step S101.

  In step S110, the control device 10 compares the current vehicle speed increase amount (difference X) with the past vehicle speed increase amount to obtain the maximum value of the vehicle speed increase amount after the start of deceleration. If the current vehicle speed increase amount (difference from the vehicle speed at the first time) is greater than the past increase amount (difference from the vehicle speed at the first time), the control device 10 proceeds to step S113; Advances to step S111.

  In step S113, the control device 10 stores the vehicle speed increase amount in the RAM 13 assuming that the current vehicle speed increase amount is the maximum. As long as the vehicle speed increase amount exceeding the stored vehicle speed increase amount is detected, it can be determined that the vehicle speed continuously increases.

  For example, in step S113, after the vehicle speed increase amount (difference X) at point D in FIG. 6 is stored as the vehicle speed maximum increase amount, the process returns to step S104, and if an increase in vehicle speed at point E is detected, step The process proceeds to S109, and further proceeds to step S110 because it is not the first increase. In step S110, the control device 10 calculates a vehicle speed increase amount at the point E. The vehicle speed increase amount (difference Y) "=" current vehicle speed (vehicle speed at the point Y) "-" vehicle speed at the first time (vehicle speed at the point C) "is obtained. Confirms that the current vehicle speed is less than the second predetermined speed (20 km / s) If the current vehicle speed is equal to or higher than the second predetermined speed (20 km / s), the process is stopped and the step Returning to S101, the control device 10 compares the vehicle speed increase amount (difference X) at the point D with the vehicle speed increase amount (difference Y) at the point E. In the example shown in FIG. Since (difference Y) is larger than the vehicle speed increase amount (difference X) at point D, the process proceeds to step S113.

  In step S113, the control device 10 stores the vehicle speed increase amount (difference Y) at the point E as the vehicle speed maximum increase amount, and proceeds to step S111. In step S110, if the vehicle speed increase amount calculated this time is not the maximum, that is, if the vehicle speed increase amount calculated this time is smaller than the vehicle speed increase amount calculated last time, the step is executed without storing the vehicle speed maximum increase amount. Proceed to S111.

  In step S111, the fuel consumption calculated at each point (point C, point D, point E) is added. That is, the fuel consumption consumed between point C and point D and the fuel consumption consumed between point D and point E are added, and the fuel consumption caused by acceleration after deceleration (evaluation) (Part of fuel consumption).

  And when driving | running is continued, it progresses to step S104 again. A process when the vehicle speed is reduced in step S104, that is, a deceleration operation is performed will be described. In this process, the control device 10 confirms that the current vehicle speed is less than the second predetermined speed (20 km / s). If the current vehicle speed is equal to or higher than the second predetermined speed (20 km / s), the process is stopped and the process returns to step S101.

  In the example shown in FIG. 6, the vehicle speed at the point F is smaller than the vehicle speed at the point E. Therefore, the timing at which the vehicle speed that proceeds to step S105 starts to decrease is the second time.

  In step S105, when the maximum vehicle speed increase amount (difference X, difference Y, etc.) stored in step S113 is less than a predetermined value (5 km / h in this example), the control device 10 calculates in steps S109 to S111. It is determined that the evaluated fuel consumption is due to the creep phenomenon, and it is determined not to be unnecessary fuel consumption during deceleration, and the process proceeds to step S106. In step S106, the control device 10 resets the evaluation fuel consumption calculated in steps S109 to S111 to zero.

  On the other hand, in step S105, the control device 10 calculates in step S111 when the vehicle speed maximum increase (difference X, difference Y, etc.) stored in step S113 is equal to or greater than a predetermined value (5 km / h in this example). The evaluated fuel consumption that has been performed is stored as an evaluation fuel consumption that has been consumed in the evaluation section between the first time and the second time, and the process proceeds to step S102, to the evaluation of driving and the presentation of evaluation results move on.

  Since the driving evaluation information providing apparatus 100 according to the present embodiment is configured and operates as described above, the following effects can be obtained.

  According to the driving evaluation information providing apparatus 100 of the present embodiment, driving during deceleration can be evaluated.

  That is, the driving evaluation information providing apparatus 100 according to the present embodiment sets a predetermined evaluation section at the time of deceleration based on a temporal change in the vehicle speed of the vehicle, and is calculated based on the fuel consumption over time. Since the driving is evaluated according to the evaluation fuel consumption consumed in the vehicle, unnecessary fuel consumption can be obtained in the evaluation section set based on the change in the vehicle speed, so the driving during deceleration is evaluated. be able to.

  When evaluating driving from the viewpoint of environmental protection, evaluate whether the driving is suitable for environmental protection by dividing it into driving states such as acceleration, deceleration, cruise, and stop (idling). For example, at the time of departure, a quantitative guideline such as “20 km / h in 5 seconds” is provided. However, at the time of deceleration, since the mode of deceleration differs depending on the influence of surrounding traffic conditions such as the distance to the stop and the distance from the preceding vehicle, a quantitative guide cannot be provided. In response to this problem, the driving evaluation information providing apparatus 100 according to the present embodiment sets an evaluation section suitable for executing driving evaluation at the time of deceleration based on a change in vehicle speed. Can be evaluated (whether or not unnecessary fuel is consumed).

  Further, the driving evaluation information providing apparatus 100 according to the present embodiment sets the evaluation section in a low speed zone where the vehicle speed is equal to or higher than the first predetermined speed and lower than the second predetermined speed. Acceleration that occurs during deceleration that does not lead to a state or stop state (acceleration repeated with deceleration in a traffic jam situation), or acceleration that occurs during deceleration in a high vehicle speed zone that is equal to or higher than the second predetermined speed (for example, a signal is generated during deceleration) It is possible to set an evaluation section in which unnecessary acceleration at the time of deceleration is performed except for acceleration necessary for traveling such as acceleration from red to blue to increase speed.

  In addition, the driving evaluation information providing apparatus 100 according to the present embodiment sets an evaluation section when the vehicle speed becomes less than the speed threshold from a speed higher than a preset speed threshold. The case where acceleration is not achieved and the vehicle is accelerated after deceleration can be excluded from the target of driving evaluation. In a traffic jam, acceleration and deceleration occur frequently, so it is difficult to evaluate unnecessary fuel consumption, and the results of driving evaluation performed under such circumstances can get the driver's empathy. Therefore, it is unlikely to help improve driving. In the present embodiment, the evaluation section is set and the driving is evaluated only when the vehicle speed is higher than the predetermined vehicle speed and lower than the predetermined vehicle speed. Therefore, fuel is wasted rather than an unavoidable situation such as a traffic jam. Acceleration during deceleration can be evaluated as unnecessary fuel consumption only in the scene.

  In addition, since the driving evaluation information providing apparatus 100 according to the present embodiment sets the second time when there is an increase in speed of a predetermined value or more after the first time, it must stop idling or creep running. Acceleration while decelerating can be evaluated as unnecessary fuel consumption only in situations where waste of fuel occurs, not in a situation where there is no waste.

  In addition, the driving evaluation information providing apparatus 100 according to the present embodiment displays the evaluation result including the evaluation fuel consumption in the evaluation section, the evaluation result including information indicating the evaluation section where the vehicle has traveled, and / or the time when the travel is performed in the evaluation section. Since the evaluation result further including the information to be displayed is output, the driver examines the presented evaluation result in correspondence with his / her driving situation by specifying the specific driving date and time and presenting the evaluation result. Therefore, the evaluation result can be used as data for improving the driver's own driving.

  Next, functions of the control device 2010 of the server 2000 will be described. When the control device 2010 of the server 2000 changes to the acceleration state between the time when the vehicle starts to decelerate and becomes less than the first predetermined speed based on the change with time of the vehicle speed acquired from the in-vehicle device 1000. Obtained from the in-vehicle device 1000, and an evaluation section setting function for setting an evaluation section based on the first time of the first time and a second time after which the vehicle starts decelerating again at a speed less than the second predetermined speed after the first time.

The description uses the description according to the first embodiment.

  Further, the database 2800 of the server 2000 has an injection amount map 2810. This injection amount map 2810 is common to the injection amount map 31 provided in the database 30 of the in-vehicle driving evaluation information providing apparatus 100 of the first embodiment.

  In addition, the information transmission function included in the control device 2010 of the server 2000 of the present embodiment, the communication device 2700 displays the vehicle speed over time, the fuel consumption over time, and the vehicle travel position over time transmitted by the in-vehicle communication device 700. To receive via.

  Note that the control device 10 of the driving evaluation information providing device 100 and the control device 2010 of the server 2000 are both ROM (in which a program is stored), like the control device 10 of the driving evaluation information providing device 100 of the first embodiment. By executing a program stored in the ROM 12, a CPU (Central Processing Unit) 11 as an operation circuit that functions as the driving evaluation system 1 and a RAM (function as an accessible storage device) are executed. Random Access Memory) 13.

  Then, the control procedure of the driving | operation evaluation system 1 of this embodiment is demonstrated. FIG. 8 is a flowchart for explaining the entire process of presenting the driving evaluation result by the driving evaluation system 1 of the second embodiment.

In step S201, the control device 10 of the driving evaluation information providing apparatus 100 acquires the vehicle speed detected by the vehicle speed sensor 501 over time, and in step S202, the fuel detected by the fuel injection sensor 400 (or the vehicle controller 300). The injection amount is acquired over time, and in step S203, the traveling position of the vehicle detected by the navigation device 200 is acquired over time. These processes correspond to steps S01 to 03 shown in FIG.

  In subsequent step S <b> 204, the control device 10 of the driving evaluation information providing device 100 sends the vehicle speed, the fuel injection amount, and the travel position to the server 2000 in association with the detection time of each information via the in-vehicle communication device 700. This information includes vehicle identification information for identifying the vehicle. The vehicle identification information is preferably a vehicle communication address (telephone number). The server 2000 includes address data in which vehicle identification information is associated with a vehicle communication address in advance.

  The communication device 2700 of the server 2000 receives these pieces of information. And the server 2000 manages information, such as a vehicle speed, for every vehicle based on identification information.

  In step S301, the control device 2010 of the server 2000 monitors changes in the vehicle speed of each vehicle.

  In step S302, the control device 2010 of the server 2000 determines whether or not the vehicle speed has been reduced to less than 20 km / h from a state where the vehicle speed threshold is 20 km / h or higher. When the vehicle speed is reduced to less than 20 km / h from a state where the vehicle speed is 20 km / h or higher, the control device 2010 proceeds to step S303 and starts the driving evaluation process.

  In step S03, the control device 2010 of the server 2000 extracts an evaluation section. The evaluation section includes a first time when the vehicle changes to an acceleration state before the vehicle starts decelerating and becomes less than the first predetermined speed, and less than a second predetermined speed after the first time. Therefore, it is between the second time when the vehicle starts to decelerate again.

  In step S304, the control device 2010 calculates the fuel consumption amount in the evaluation section. Specifically, the control device 2010 executes the fuel that is executed from the first time to the second time based on the time-lapse vehicle speed acquired in step S301 and the time-lapse fuel injection amount acquired in step S302. An integral amount of injection is calculated as an evaluation fuel consumption amount in the evaluation section. This fuel consumption calculation method is the same as the method described with reference to FIGS. 5 and 6 in the first embodiment.

  Moreover, in step S305 parallel to this process, the control apparatus 2010 specifies the positional information on an evaluation area. Specifically, the control device 2010 identifies an address or intersection name, facility name, etc. that identifies the travel position that travels between the first time and the second time based on the travel position with time acquired in step S303. The POI information of is acquired.

  In the next step S306, the control device 2010 evaluates the operation. Specifically, when the fuel consumption amount in the evaluation section is greater than or equal to a predetermined value, the control device 2010 evaluates that the driving at the time of deceleration is not driving that contributes to environmental protection (so-called eco driving). On the other hand, when the fuel consumption amount in the evaluation section is less than the predetermined value, the control device 2010 evaluates that the operation at the time of deceleration is an operation that contributes to environmental protection (so-called eco operation).

  Thereafter, in step S307, the control device 2010 determines whether or not traveling has ended. Specifically, when the key-off signal is detected (Yes in step S205), the vehicle-mounted driving evaluation information providing apparatus 100 sends the key-off signal to the server 2000 (step S206). When the control device 2010 of the server 2000 acquires the ignition key-off information sent from the vehicle side, the control device 2010 determines that the travel has ended, and proceeds to step S308. On the other hand, if the ignition key-off information is not acquired, the control device 2010 determines that traveling is continuing and returns to step S301.

  In step S308, the control device 2010 of the server 2000 transmits the driving evaluation result to the vehicle. The transmission destination is a transmission destination associated with the vehicle identification information transmitted in step S204.

  The on-vehicle driving evaluation information providing apparatus 100 presents the received driving evaluation result to the driver via the display 20 and / or the speaker.

  As a modification of the driving evaluation process in the driving evaluation system 1, the evaluation section setting function may be included in the control device 10 of the in-vehicle driving evaluation information providing device 100. In this case, the set evaluation section, that is, the first time and the second time are sent to the server 2000. The server 2000 calculates the evaluation fuel consumption of the evaluation section defined by the received first time and second time.

  Since the driving evaluation system 1 of the present embodiment is configured and operates as described above, the same effects as those of the first embodiment described above are achieved.

  In addition, since the operation evaluation system 1 of the present embodiment executes evaluation section setting, evaluation fuel consumption calculation, and evaluation on the server 2000 side, it is not necessary to add new hardware to the in-vehicle device 1000. In addition, it is possible to prevent the on-vehicle apparatus 1000 from being subjected to a processing load.
